“…The mastication muscle group is innervated by the mandibular branch of the trigeminal nerve. Barbarino et al (2008Barbarino et al ( , 2009 [60,61] presented an anatomically detailed FE model of the face of a 27 year old male. In their work, most facial soft tissue structures including muscles of the masticatory system were semiautomatically reconstructed from magnetic resonance images.…”

A detailed numerical implementation within the FEM is presented for a physically motivated three-dimensional constitutive model describing the passive and active mechanical behaviors of the skeletal muscle. The derivations for the Cauchy stress tensor and the consistent material tangent are provided. For nearly incompressible skeletal muscle tissue, the strain energy function may be represented either by a coupling or a decoupling of the distortional and volumetric material response. In the present paper, both functionally different formulations are introduced allowing for a direct comparison between the coupled and decoupled isochoric-volumetric approach. The numerical validation of both implementations revealed significant limitations for the decoupled approach. For an extensive characterization of the model response to different muscle contraction modes, a benchmark model is introduced. Finally, the proposed implementation is shown to provide a reliable tool for the analysis of complex and highly nonlinear problems through the example of the human mastication system by studying bite force and three-dimensional muscle shape changes during mastication.

Facial reconstruction can be used as a forensic technique to identify a person, when no other identification method is applicable. The facial soft tissue thickness applied to the skull is crucial when performing an accurate facial reconstruction. Historically, scientists developed several techniques to measure the soft tissue of the face. It was their aim, to build a database of a unique point-set, differentiated by gender, age, ethnic origin, BMI. All used a limited number of landmarks and an inaccurate measuring technique. We developed a contact-free and precise measuring technique, using low-dose CT and holographic data. Due to the extremely short exposure time, the holographic measurement is very precise. We lay out our first experiences to create a facial soft tissue layer map of the face.

“…Most models are uni-or bi-lamellar, composed of layers which often have a constant thickness and which show linear isotropic mechanical behavior (see for example [5,4,9,14,10] for the face or the breast). They differ considerably from the genuine architecture of the human SSC, which is supported by a complex three dimensional collagen network causing a non-linear anisotropic mechanical behavior.…”

Abstract. The aim of this work is to build a 3D geometric and mechanical model of the skin/subcutaneous complex (SSC) which could be adapted to the different parts of the body and to the morphological parameters of the patient. We present first the anatomical pattern of the SSC. Then, we propose a hybrid model which combines volume, membranous and unidimensional models. The complex internal structure of the SSC is automatically created by a procedural process. All the models are defined by some parameters which can be easily measured by medical imaging. We describe several preliminary experiments which show how this hybrid method models realistic geometrical deformations and physical behaviors and could be used for surgery simulation and planning.
